Fix#7838. Add docstrings and privatize _subprocess implementation details.
Since CREATE_NEW_* are used for the creation flags of a subprocess, they
were added to __all__. The rest of the previously exposed attributes are
now qualified by _subprocess.ATTR rather than importing *.

This is still messy, realistically PC/_subprocess.c should never cast pointers
to python numbers and back at all.
I don't have a 64-bit windows build environment because microsoft apparently
thinks that should cost money. Time to watch the buildbots. It builds and
passes tests on 32-bit windows.
objimpl.h, pymem.h: Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE}
to PyObject_{Free, FREE} in a release build. They're aliases for the
system free() now.
_subprocess.c/sp_handle_dealloc(): Since the memory was originally
obtained via PyObject_NEW, it must be released via PyObject_FREE (or
_DEL).
pythonrun.c, tokenizer.c, parsermodule.c: I lost count of the number of
PyObject vs PyMem mismatches in these -- it's like the specific
function called at each site was picked at random, sometimes even with
memory obtained via PyMem getting released via PyObject. Changed most
to use PyObject uniformly, since the blobs allocated are predictably
small in most cases, and obmalloc is generally faster than system
mallocs then.
If extension modules in real life prove as sloppy as Python's front
end, we'll have to revert the objimpl.h + pymem.h part of this patch.
Note that no problems will show up in a debug build (all calls still go
thru obmalloc then). Problems will show up only in a release build, most
likely segfaults.
